kosong

Kosong is a word found in Indonesian and Malay that means empty, vacant, or unoccupied. It functions as an adjective to describe spaces or containers that are not filled, such as a room, a box, or a seat. The term also appears in phrases signaling absence or lack, and can be used as a noun in certain contexts to denote a blank or vacancy.

As a verb-related form, mengosongkan means to empty out or to clear something. The base noun kosong is used in everyday language to refer to emptiness or blank spaces, with common phrases including ruang kosong (empty space), halaman kosong (blank page), and kolom kosong (blank column). In signage, forms, and digital interfaces, kosong frequently indicates an unfilled field or a space that has yet to be completed.

In numerical contexts, Indonesian and Malay generally use nol to denote zero in formal mathematics and technical writing. Kosong is commonly used in everyday speech to convey the concept of emptiness or absence, and it may appear in casual descriptions of numbers (for example, describing a score or a count in a nontechnical way) or in phrases that emphasize a lack rather than a precise numeral. The word is widely understood across Indonesia and Malaysia and appears in various regional expressions, educational materials, media, and everyday communication.
